This book is manual of the principles and subtleties of Qur'anic tafsir. In it the author outlines the five fundamental sciences that the Qur'an contains: the science of judgements (ahkam), reminding others of the Favours of Allah, the Days of Allah and the Life after Death, and giving particular attention to the science of polemics. He also reviews the other sciences of tafsir such as the circumstances of revelation (asbab an-nuzul), abrogating and abrogated ayat (an nasakh wal mansukh) and unusual words and phrases of the Qur'an (ghara'ib Al-Qur'an), before concluding the book by looking at the extraordinary and miraculous aspects of the Noble Book, and a final chapter on the meaning of the letters of the Arabic alphabet.
